NASA’s James Webb Space Telescope Could Study Planet 9

Evidence of an unknown planet orbiting far from the Sun was observed from an anomaly in the orbits of Kuiper Belt objects. This new planet, named Planet 9, is said to be very large but too far for ground based telescopes to detect it. Once it’s launched, Nasa’s James Webb Space Telescopes, the world’s most powerful telescope, would be able to fully characterize this new planet.
